Kevin Dunn has been tapped for a major recurring role on Matthew McConaughey and Woody Harrelson’s upcoming eight-episode HBO drama series True Detective. The high-concept project is described as an elevated serial narrative with multiple perspectives and time frames. It centers on two detectives, Rust Cohle (McConaughey) and Martin Hart (Harrelson), whose lives collide and entwine during a 17-year hunt for a serial killer in Louisiana. The investigation of a bizarre murder in 1995 is framed and interlaced with testimony from the detectives in 2012, when the case is reopened. Dunn will play Rust and Martin’s boss, the fair but tough 3rd Squad Homicide Commander Maj. Ken Quesada. Dunn, repped by the Gersh Agency and Lighthouse Entertainment, already is recurring on another HBO series, comedy Veep, as the President’s Chief of Staff. On the big screen, he will next be seen in The Frozen Ground, Jobs and Diego Luna’s Chavez.

Is this the next Angus T. Jones? Youngster Blake Garrett Rosenthal has been cast opposite Anna Faris and Allison Janney in Chuck Lorre’s CBS comedy pilot Mom. The multi-camera project, which he co-wrote on spec with two members of his Two And A Half Men team — executive producer Eddie Gorodetsky and story editor Gemma Baker — centers on Christy (Faris), a newly sober single mom who tries to pull her life together in Napa Valley. Blake will be playing, Roscoe, Christy’s 8-year-old son. This marks Lorre’s first pilot with a kid as one of the main characters since Two And A Half Men. Paradigm-repped Rosenthal co-starred in the potential Office spinoff The Farm, which didn’t forward, and appeared in Bridesmaids and on Fox’s New Girl.
